How to choose the best milkweed seeds for monarchs

Start with the species, because the best milkweed seeds for monarchs are the ones that fit your region and your site. Monarch caterpillars feed on milkweed, so the plant you choose should suit your climate. Check the zones listed on each product and compare them with the USDA Plant Hardiness Zone Map.

Next, look at soil moisture. Several listings here describe wetland species such as swamp milkweed, while others are described as drought tolerant and suited to sandy or dry ground. Matching the species to your site usually matters more than the size of the packet.

Then compare seed counts and coverage claims. A large count does not tell you how many plants will establish. Some packets list coverage in square feet, while others only list seeds per packet. Read the spacing notes before you buy.

Germination instructions vary. Many listings say milkweed benefits from a cold, moist period, which you can get by sowing outdoors in fall or by chilling seed in the refrigerator before spring. Follow the instructions on your packet. Expect some waiting: some butterfly milkweed listings say plants may take two to three years to flower. Milkweed also dislikes transplanting, so direct sowing is often advised.

Finally, check the safety notes. One listing says the milky sap is toxic to many herbivores. If pets or children may nibble plants, ask a veterinarian or your local extension office for guidance. For more on pollinator habitat, see the Xerces Society’s pollinator conservation resources and our Pollinator-Friendly Plants category.
